Pushrods are fixed length and must be used with the OEM solid type, adjustable lifter assembly. Available in chromoly and aluminum. Chromoly pushrods are thinner and have better flex resistancy than aluminum. Aluminum is lighter than chromoly and will reduce inertia mass. But for heavy duty service, like racing and/or high lift cams with high pressure springs it is still advised to run chromoly pushrods. Note: See 906693 for aluminum pushrods.
